Blending L HA, R S2+HA10%, G O3+HA5%, B O3+HA10%

Il canale HA (maggiormente presente in questa nebulosa) usato sia per rafforzare la composizione RGB e sia come Luminanza, mi ha permesso di abbassare il rumore e migliorare i dettagli più fini ed esterni della nebulosa. Ho effettuato molti tentativi di blending prima di decidere per questa composizione che più mi appagava. Elaborazione finale morbida.

HA channel (the deepest of the three) allowed me to keep down the noise, helping to get a stronger RGB composition. I used HA as Luminance as well giving a better feel on the finest details. After a few tries, I chose this kind of blending, leaving the final processing the smoother I could.
